为确保加氢站可靠运行,需对加氢站内设备的维修策略进行优化分析。结合设备在运行周期的后期状态退化、故障率上升等客观趋势,引入混合故障率模型,建立一种包含最小维修、预防性维修与预防性更换的设备成组维修方法。通过对加氢站内设备关键度的定量比较,以维修成本、可用度为目标分别建立相应的设备成组预防性维修模型,可更好平衡设备可靠性和预防性维修成本之间的关系,是传统预防性维修模型的重要扩展。并结合实例,验证模型的有效性。
Abstract
To ensure that the reliable operation of the hydrogen refueling station, the maintenance strategy for the station's equipment needs to be optimized and analyzed. In conjunction with the objective patterns of equipment degradation and failure rate increase in the later phases of the operating cycle, a hybrid failure rate model is developed to establish a group maintenance technique that incorporates minimum maintenance, preventive maintenance, and preventive replacement. By quantitatively comparing the criticality of the equipment in the hydrogen refueling station, the corresponding equipment group preventive maintenance model is established with the objectives of maintenance cost and availability, which can better balance the trade-off between equipment reliability and preventive maintenance cost, representing an important extension of the traditional preventive maintenance model. The model's validity is also confirmed through case studies.
